Maple

Hello there,

Here is a set of non-linear equations:

The 'fsolve()' command was able to come up with a solution.

Then, when 'f9n10 := V[t] * (Ix[c1] - Ix[c2]) + TrainLoad = 0;' becomes 'f9n10 := V[t] * conjugate(Ix[c1] - Ix[c2]) + TrainLoad = 0;',

the command ('fsolve()') refused to produce a solution.

Would you tell me how to make the 'fsolve()' command work with the 'conjugate()' operator?

Thank you,
